Definitely something odd with her right thumb and index finger though. Her right upper arm looks too short, and possible her left upper arm a teeny bit too long -- look at the elbows. I'd also suggest making her arms a little more muscular; that suit and arm cannon have to be heavy.

This is reminding me that I scanned a drawing my sister did of Samus at home only the scan was so large that I haven't been able to look at it without turning my computer into molasses... several years ago. Maybe I have something that would show it now.
